Our take
Choose the ST-TCHCRM as a data and card-reader hub when its short USB-C lead suits the desk and you do not need video output or laptop charging. The exact USB-A port count is not stated in the accessible product text, and the two card formats cannot be used at once.
A USB-C laptop user who wants data ports and occasional SD or microSD transfer close to the computer, without needing display docking or laptop charging..
It is not for an external monitor, Ethernet, simultaneous SD and microSD access, standalone phone charging, or a setup that needs a longer detachable cable.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Satechi maps ST-TCHCRM to the Space Gray desktop hub and documents its attached USB-C cable.
- The setup guide identifies USB-A data and both SD and microSD slots, including their use limits.
- The product is clearly described as data-focused rather than a PD charging dock.
What to weigh up
- The accessible text does not give the exact number of USB-A ports.
- SD and microSD cannot be used simultaneously.
- No HDMI, Ethernet or host-charging input is listed, and the historical Amazon ASIN is not mapped.

Full review: how the features affect your choice
What the features mean for you
Use it for USB data and card transfer rather than display docking
The ST-TCHCRM is a USB-C-connected desktop hub for USB-A peripherals and removable media. Satechi lists no HDMI output, Ethernet port or PD input for this model. It can suit a desk where a keyboard, storage device and card transfer matter more than monitor docking or charging the host. If video or wired networking is part of the setup, choose a model that explicitly lists those functions rather than assuming this combo hub includes them.
Plan for one card format at a time
The official quick-start guide identifies both SD and microSD slots and says they cannot be used simultaneously. That is useful for occasional transfers from either card type, but it does not support copying from both formats at once. Check which card the workflow needs first and allow time to switch slots if a project uses both. The product's USB-C host cable does not change the card-reader concurrency limit.
Treat 5Gbps as an interface rating, not a benchmark
Satechi describes USB-A data for USB 3.0, 2.0 and 1.1 peripherals and lists transfer rates up to 5Gbps. The accessible text does not enumerate the exact USB-A port count or provide per-port simultaneous test results. Attached drives share the host connection, and their own capabilities also matter. Use the rating to identify the supported interface class, not as a guarantee of sustained copies at that rate.
Measure the route for the fixed 12.5-inch cable
The attached USB-C cable is approximately 12.5 inches and is not detachable. That can keep the hub close to a laptop or desktop, with the card slots and USB-A ports within reach. It also limits placement distance if the computer sits behind a monitor or in a vertical stand. Satechi lists a body about 5.38 by 1.96 inches and 4.3 ounces; measure the cable path and available desk space before relying on a particular position.
Search by the exact SKU and color
Satechi's product page identifies ST-TCHCRM as the Space Gray SKU, while the historical B0BVCSXM7L page could not be read. The model and color are supported, but that ASIN is not established as the current exact offer. Search by the tagged model and color, then compare the official port diagram. This review uses manufacturer product and setup information; it makes no claim of personal testing, current price, stock, sales or customer-review consensus.

Before you buy
Can the SD and microSD slots operate simultaneously?
No. Satechi's guide says the two card slots cannot be used at the same time.
Does the hub charge a laptop through USB-C PD?
No PD input is listed; Satechi describes data transfer rather than standalone charging.
Is the attached cable removable?
No. The product page describes an attached cable about 12.5 inches long.
How many USB-A ports are there?
The accessible official text does not enumerate the count, so it remains unknown here.
